What is the specific heat ratio, when γ = Cp/Cv and the degrees of freedom are 3 and 5?

Answer: 5/3
Explanation

Let’s assume two cases:

  • If
    f = 3
    (monatomic gas), then:

  • If f=5f = 5 (diatomic gas), then:

Since the question asks for γ when degrees of freedom are 3 and 5, and γ = Cp/Cv, then:

  • For f = 3 → γ = 5/3
